7 Claims. (Cl; %257? The present 'inven-ti-on rela-tes to 'anzi improved' ca'r stop "adapted toqbe zi stalled on afirail of" a traclt way for halting the movem-ent of rail-" ca'rs or other rolling stock therealong; The device of"the invention is -espec-ial lyi suitable for; use on mine trackways where it 'is neces sary to position rail-cars on tlie trackway at=desirecl points forloading and unloading particularly"wherethe trackway runs-along avgrade;

It is an object of the A presentinvention toprovide-am improved car stop which is of simple',-rugged' and in expensive construction and which may be easily installed on a" rail of atrackway;

It is another object of th'e' present invention topro=-' v-ide'l an: improved car stop which after installation ona rail of ai trackway iscapable of: being moved; T byasimple manual manipulation, from an operative stopping =-position engageable by a car wheel toan inoperative position clear offthe rail to permit unobstructed"movement of rolling stockalo'ng the'trackway:

It is :a further object of the presentzinvention to"-pro--- vide an improved car stop of the character described which is provided with automatic latching means for positivelylocking the car stop in operative position.

These and votheruobjectsawill becomemore apparent after referring" to the following specification and attached drawings, in" which:

Figured is -a-viewin perspective;

Figure'2 is an end view;-

Figure '3 isaa side elevational view "looking toward the outer side "ofthe rail-onwhiehthe stop of the invention is installed;

Figure 4 is a view similar to Figure 3 looking toward the inner side of the rail;

Figure 5 is a cross sectional view taken on the line V-V of Figure 4; and

Figure 6 is an end view showing the stop of the invention in inoperative position clear of the rail.

Referring more particularly to the drawings, reference numeral 2 designates a base block having spaced end walls 4 connected together by an angle plate 6 clamped against the bottom of the base flange of a rail R be tween a pair of supporting ties T. It will be noted that for purposes of this description the side of the rail R toward the ends of the ties is referred to as its outer side while the opposite side of the rail, that is, the side remoe from the ends of the ties, is referred to as its inner side. When the base block 2 is clamped into position under the rail R, in the manner to be described, the end walls 4 extend in a plane normal to the longitudinaal axis of the rail, as best shown in Figure 5. The base block 2 extends under the base flange of the rail R with the end walls 4 and the angle plate 6 projecting outwardly beyond the outer side of the rail. A housing 8 having spaced side walls 10 is fitted over the base block2 with its side walls 10 closely adjacent the end walls 4 of the base block. A vertical cheek plate 12 is disposedon each side of the housing 8 closely adjacent the side walls 10. The cheek plates are fastened to the 2,8213% R mmed Feb. 4, 1958 P NE and extending in;=a horizontal "plane therefrom-overlyingthe top surfaces of the ties. The-flangesare spikedto the tiesadjacent' the outer edge of-the -base; flange of the rail. The bottom. portions; of the cheek plates ex-' tend 'across-the bottom-of th'erail R. As shown in Figure 4,'--an edge 4a of eachof the end walls 4 extends vertithe' topof the rail-R when-the device is in operative positionas will be more fully explained hereinafter.

The housing 8 is pivotally connected with the-base block? and cheek plates 12 by means of two hinge pins:

18fwhich are fitted-through suitable aligned openingsin the adjacent cheelcz-plates 12, side walls 10 and I end walls-4 on eaoh side of the housing 8. The hinge pins 18- are -co'-axiallydisposed under-the rail R.

Each of the edges 4a of the end walls 4 is provided;

on its upper-v port-idmwith a threaded stud- 22 which extendsunorma-l to the hinge'tpi-ns -ls and projects from unde'r the=inner side of the raili The edge IZa-ofeach of the cheek plates 12 is provided-with a -similar stud 24 which extends parallel with stud 22 on the-adjacent pair of s'tuds 22 and -24 in clampingmosition on the baseflange of theraiPRi The rail..clamps 28 are held-in.

positionb'ymeans oflock nuts 301' 'A rail hook clamp 32 which engages thebase-flange ofthe-rail R 'is 'welde-d" or otherwise rigidly-mounted on the upper-surfaceof each of the end walls 4 'and aids in clampingthebase' block securely onto the rail.

Each of-the side walls 101s provided with anelongated slot 34 from which projects theends of a horizontalbar 36 mounted within the housing -8 parallel with and above the longitudinalaxis of the base-block 2'. Each ofthe cheekplates 12 is providedwitha transverse 'grooveor' slot38 in the upper portion=thereof for-freceiving theprojecting'en ds of the bar sswaen the 'deviced's -in'operating position as best-shown inFi'guresland- 2; 5 A' stem' 40 *is welded or otherwise 'attached to the barfib intere mediate its ends. The stem 40 extends from the bar 36 and projects outwardly and upwardly of the housing through a nipple or socket 42 which is integral with and surrounds an opening in the upper wall of the housing.

A helical compression spring 44 is mounted around the stem 40 with one end bearing against the bar 36 and its other end bearing against the inner surface of the top of the nipple 42. The spring 44 serves to constantly urge the bar 36 away from the nipple 42 and thus positively lock the bar in position with its ends engaged in the slots 38 when the housing 8 is in operative position. The stem 40 is manipulated manually to lift the bar 36 against the pressure of the spring 44. The stem 40 has a handle 41 attached to its upper end to facilitate manipulation thereof. If desired, a guide bracket 43 having a hole therein may be attached to the outer face of the stop member 20 for guiding the vertical movement of the stem 40.

The stop member 20 is preferably fabricated from two plates welded together, as is shown in Figure 5. The plate making up the outer side of the stop member 20 is provided with an extending angular portion 46 on the bottom thereof which fits against the side of the rail when the device is in operative position. The extending portion 46 tends to limit the pivotal movement of the housing so as to insure proper positioning of the stop member 20 when the housing 8 position on the hinges 18.

The housing 8 is provided with 'a stop member 20' which projectsi upwardly from t is pivoted into operative In normal operating position the bar 36 has its ends fitted in the slots 38 and the stop member 20 projects vertically upward of the rail R so as to be engageable by the wheel of a rail car traveling on the rail. When it is desired to place the device in inoperative position clear of the rail R the handle 41 is grasped and the stem 40 is pulled upwardly to raise the bar 36 and lift its ends out of slots 38. The housing 8 is then pivoted downwardly on the pins 18 so that the stop member 20 extends outwardly from the rail R as shown in Figure 6. When the stop member is in this position the wheels of a car or other rolling stock may travel over the rail R unimpeded. Each of the cheek plates 12 is provided with an arcuate edge 48 on which the ends of the bar 36 ride as the housing 8 is pivoted on the hinge pins 18. A shoulder abutment 50 may be provided on the bottom of each of the arcuate edges 48 for limiting the downward movement of bar 36, as shown in Figure 6. To return the car stop to operative or up position, stop member 20 is raised toward the rail until the extension 46 engages the outer side of the rail. When the stop member reaches this position the spring 44 exerting pressure on bar 36 forces it downwardly so that its ends are engaged in the slots 38 and the device is thus automatically locked in position.

While one embodiment of my invention has been shown and described, it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.

I claim:
